it seems like they are/should be. I'd like to use one of the dirty sands available in game but I'm not sure how to find it or get it in caw.
---------------------------------------------------------------solved this part, i think

Also.. does anyone know where I can find opacity maps to hide the sidewalk gap next to streets. I found a link but its attached to an ad.fly and I'd...rather not click it

or the middle one
for example

Solved my own issue just toying around ; u ;

This set has multiple textures for road pavements, sidewalks, opacities, lines, crosswalks, etc. One of these opacity maps is a completely invisible one, which the file itself is a 64x64 .dds image file with a solid black color. It also has rough opacities which can be useful to make the sidewalk the same material as the road, then use these opacities to make a shoulder. They are made also as a 64x64 .dds file with solid black as invisible, solid white as fully visible.
I use these texture for almost every road. The only ones I try to avoid are the line decals, as for some reason, if you use any yellow, they appear as white in low LOD, which is annoying.
